A baler knot is an alternate term for the classic square knot. The process to tie a baler knot is simple, if you remember the phrase "right over left, left over right". A finished baler knot has a square appearance and tightens as the ends pull tighter. The term baler knot comes from farmers using this type of knot when joining two sections of twine together in a hay baler. This knot holds tight, without the worry of it loosening while making the bales.
Hold one end of the string or rope in one hand, and the opposite end in the other hand.
Bend the left rope inward and hold it. Bend the right rope inward and over top of the left rope. Wrap the right rope around and under the left, and then pull the two ends tight to create a tight criss-cross.
Bend the right rope inward and hold it. Bend the left rope inward and over top of the right rope. Wrap the left rope around and under the right, and then pull the two tight to form a second criss-cross that creates the knot.
The first step of tying the baler knot is the same as the beginning step of tying a shoe.
